The Shins "Wincing the Night Away"

I've always thought The Shins' Wincing the Night Away album art was really cool. The color scheme is simple and the designs on it are very abstract, yet eye catching. I've been trying for so long to figure out what exactly it is on the cover, but I've prett ymuch accepted it as just an interesting design piece with a series of shapes and lines. The bottom figure has some kind of plant radiating out, with a series of tube-shaped figures coming out of the one on top. Everything appears to have been drawn in with a pen, and overall the abstract album art is eye catching, despite it's neutral color scheme.
